The reason I ask is, we turned everything off and the electrical plug still read Alive when we put the volt tester in it.
We have new GFI's to install, but don't want to get shocked. Ha!
Thanks for your help!
p.s. Or...do we need to disconnect our batteries also? We are electrically illiterate, so be kind.
AC and DC should be on two seperate panels.
DC current is coming from your battery bank. usually many of the systems on your boat are operated off the DC panel. It may be further hooked into an A/B/combiner switch for seprating the house and starting banks.
AC Panel may have switches controlling the outlets ( GFI for saftey). Many time they are daisy chained and there is a switch for the starboard ones and one for the port ones if you boat is large enough. Anthing running off standard electricity like home with a plug will work on the outlets when you are connected to shore power. Many people have a water heater which can be used from the AC panel side as well as engine. Some have refrigeration which is dual AC and Dc ( not as common).
The way most people get AC current while anchored or underway
is through an inverter which converts the DC ( battery current) to AC, however most of our boat is run off of DC.
AC Breaker is usually either 1 30amp or two 15 amps bonded together. That will turn the power off on the boat, however there will be AC (shore) power to that breaker. If you wish to turn it off to the boat, trip the breaker at the pedestal.
As a side note, If you have a charger for your batteries and it is turned on by use of switch on the AC panel. By powering down the panel it will not operate.
Would be advantagous to purchase Nigel Calders book and read about it as the electrical system on your boat can be expensive and most issues and upgrades can be done yourself much more cheaply.
